    Density is the mass of a substance per unit of volume. It is used to measure the compactness of a substance, and is commonly expressed in g/cm³, or lb/ft³. The density of a sample is expressed with the Greek letter "ρ" (the Latin letter D can also be used) and is calculated as: ρ = m / v For example, if you fill 500cm³ of a sample into a glass beaker, and the mass weighs 1000g, then the density would be: ρ = 1000g/500cm³ = 2g/cm³

    The density of material shows the denseness of that material in a specific given area. A material’s density is defined as its mass per unit volume. Density is essentially a measurement of how tightly matter is packed together. It is a unique physical property for a particular object. The principle of density was discovered by the Greek scientist Archimedes.  It is easy to calculate density if you know the formula and understand its related units.
